Hi Sam,
The test appears to be failing because it thinks that the .debug_macro
sections,
and their associated .rela.debug_macro sections do not contain debug
information
and as a result, should not appear (with contents) in a file that has been
stripped of everything but debugging:
Expected SHT_NOBITS type for .debug_macro
Expected SHT_NOBITS type for .rela.debug_macro
FAIL: --only-keep-debug for ELF relocatables
The reason that the test thinks that these sections do not contain debug info
is because they are part of a section group. The test code runs readelf over
the before-being-stripped version of the file and looks for any section with
either the ALLOC or GROUP flags set. Any such section found is added to a
list of non-debug sections:
if { $type != "NOTE" && [regexp {[AG]} $flag] } {
lappend non_debug_sections $name
But two of the .debug_macro sections are part of a group:
[14] .debug_macro PROGBITS 0000000000000000 00070f 00001a 00 0 0
1
[15] .rela.debug_macro RELA 0000000000000000 001ed8 000048 18 I 29 14

[16] .debug_macro PROGBITS 0000000000000000 000730 000038 00 GC 0 0

[19] .rela.debug_macro RELA 0000000000000000 004818 000090 18 IG 29 18

(I assume that this is normal behaviour for gcc when it is creating
.debug_macro
sections).
So I think that the logic in proc keep_debug_symbols_for_elf_relocatable
in binutils/testsuite/binutils-all/objcopy.exp needs to be updated.
Would it be possible for you to upload a copy of the unstriped version of
testprog.o that is triggering these results ? The version of gcc that I
am using does not generate .debug_macro sections, so I cannot test any
changes
that I make using my own compiler.
Cheers
Nick
